Hi,
Brief background...I am not a trained C programmer but am the poor soul left to update legacy C programs. One particular program requires use of BTRV API (instead of Scaleable SQL API) due to impending upgrade to Btrieve 8. The C compiler is Microsoft version 6.00A and the Linker is version 5.10.

My first problem is understanding the correct syntax for linking two objects?

The procedure I use is to open a DOS window, run a batch file that sets up the path, includes, etc. and then run a batch file that does the compile and link.

Firstly, I compile btrapi.c (compile only) to create btrapi.obj using this:
cl -c /AM /Zp /Od btrapi.c
This works fine, as far as I can tell, apart from three name truncation warning messages.

Then I compile and link the application program. Originally, when just one object, I used this supplied batch file :
cl -c /AM /Zp /Od xxxxxx.c
link xxxxxx.obj, xxxxxx.exe,, xqlintf.lib, /ST:10240 /NOE
[Note, I have masked the application name].

Now, with the additional object, I have tried variations such as
cl -c /AM /Zp /Od icrsex1a.c
link xxxxxx.obj, btrapi.obj, xxxxxx.exe,, xqlintf.lib, /ST:10240 /NOE
or
cl -c /AM /Zp /Od icrsex1a.c
link xxxxxx.obj btrapi.obj, xxxxxx.exe,, xqlintf.lib, /ST:10240 /NOE
but
get errors. I'll post the errors later, once I know and have tried the correct link method.

Many Thanks....

I just use cl for everything:

Using defaults (for compiler and linker options):

1. cl -c btrapi.c gives btrapi.obj
2. cl -c xxxxxx.c gives xxxxxx.obj
3. cl xxxxxx.obj btrapi.obj gives xxxxxx.exe (unless there are linker errors like undefined variables/functions or multiply defined variables, etc.)

If you need extra linker options and libraries use /link on the cl command line, and you can pass them as follows:

cl xxxxxx.obj btrapi.obj /link /STACK:10240 /NOENTRY


I don't see why you couldn't use the link command by itself, but, depending on the version of link you have, it may not recognize "/ST" for "/STACK" and "/NOE" for "/NOENTRY". If I just enter "link" without any arguments it gives me a list of options. (Part of bewhiskered Visual Studio version 6.)

Thanks Dave,
I'll try that out tomorrow as it's gone home time here!

Cheers,

If by /NOE, you meant /NOENTRY, What's up with that? Is the target file .exe or .dll? (Just curious.)

Regards,

Dave

/NOE means no extended dictionaries

This prevents extended library searches which sometimes cause
errors whilst linking

OK, first try was
cl icrsex1a.obj btrapi.obj xqlintf.lib

This gave me....

I think it may have worked!
Will have to test program out now, will let you know.
